UNITED STATES PHILIP VI'VIANO, OF ST. LOUIS, MISSOURI.

WEIGHING SCALE.

Application led August 27, 1925,

This invention relates to an improved weighing scale of the type found more particularly in public places, wherein a coin is frequently used for controlling the same.

In the present invention it is immaterial whether coin control means be utilized, the novelty residing more particularly in the particular shape of the casing, the provision of a rotary calibrated indicator, and novel operating means therefor.

More specifically, it is an object to provide a rotatably mounted disc which is confined in an especially constructed housing, this disc having numbers on its periphery visible through a sight opening to indicate the weight of the occupant of the scale, there being rack and pinion means associated with the central portion of the disc, a de` pending operating rod, and adjustable weights associated therewith for rendering the structure more or less sensitive, as the case may be.

Other features and advantages of the in` vention will become apparent from the following description and drawing.

In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a side view with a portion broken away, and shown in section to disclose the novel features of the invention more plainly.

Figure 2 is a fragmentary sectional and elevational view of the lower portion of the scale showing the relation of parts more particularly.

Referring to the drawings in detail the reference character 1 designates a base from which a standard 2 rises vertically. The reference character 3 indicates a vertically elongated casing or housing, 4 indicates a hollow platform, and 5 adepressible standing plate. The platform is pivoted at 6 to the intermediate portion of the standard and is pressed out to a horizontal position by the coil spring 7. It should be noted that the upper portion of the housing is comparatively narrow in side elevation, while the lower portion is increased in size, considerably as indicated at 7a. This enlarged portion, provides a substantial ledge at a point intermediate the housing, and this ledge is formed with an elongated sight opening 8,

disposed on a plane to allow the occupant Serial No. 52,806.

a rotary disc 9 on the inside of the housing. This disc is mounted for rotation in any appropriate manner, and is provided on its periphery with graduated scale numbers. Referring now more particularly to Figure 2 itwill be seen that the disc is rotated by a pinion 10, fixedly mounted on the shaft thereof, there being a vertical rack bar 11, the teeth of which are in mesh with the teeth of the pinion. Connected to this rack bar is a depending operatinor rod 12, which eX- tends down into the ho low platform, and is connected with conventional operating means (not shown). Pivoted at 13 on the housing is a rockably mounted arm 14 having a screw threaded end portion upon which a` weight 15 is adjustably mounted. Then there is an extension 16 projecting from the point of pivot, this stem being screw threaded t0 adapt it for reception of the adjustable weight 17. These weighted bars are connected with the central portion of the operating rod 12 through the medium of a link 1S.

In operation, it is plain that when the rod 12 is pulled outwardly under the action of the operating means in the hollow platform, it acts on the pinion through the medium of the rack bar 11 to rotate the rotary disc 9, and to bring the scale numbers into registry with the sight opening 8, thus indicating the weight of the occupant. The action of parts may be adjusted by proper manipulation and regulation of the weights and 17.

It is thought that by considering the description in connection with the drawings, persons familiar with weighing scale struc` tures will be able to obtain a clear under` standing of the invention. Therefore, a more lengthy description is thought unnecessary. f

While the preferred embodiment of the invention has been shown and described it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.

Certain details herein shown are not described and claimed, the same being the subject matter of a divisional application which matured into Patent No. 1,57 0,87 2 of January 26, 1926.

Having thus described the invention, what I claim as new is:-

1. In a weighing scale structure, a vertically elongated housing, a base disposed llO beneath and connected with said housinv, said housing embodying a relatively narrow upper portionA` and a widened lower portion7 said widened lower portion forming a ledge at the central portion of the housing, and said ledge haring sight opening, a disc rotatably mounted in the housing beneath said ledge, the periphery of the disc being provided with scale numbers visible through said opening, a pinion on the shaft of the disc, a rack bar in operative connection with the pinion, an ope-rating rod connected with the rack bar, a pivotally `mounted ,coi'interlialancing device embodying screw threaded portions, and Weights on the screw threaded portions.

2. In a weighing scale of the class described, a verticaly elongated housinv, a base disposed beneath and connected with "said housing, said housing embodying a relatively narrow upper portion and a comparatively wide lower portion, said widened lower portion forming a ledge at about the center 'of the housing, and said ledge having a sight opening'forlned therein7 and a graduated Vsealerdisk rotatably mounted in the housing and having the graduations thereon located to render them visible through said sight openinff.

In testimony whereof I affix my signature.
